  • the position of a casing 45 enveloping the connecting rods 22 and 29 has also been shown in dashed lines, the position of maximum overall width corresponds to the case where the connecting rod 29 is substantially perpendicular to the axis 33.
  • the fact that the lower link 29 is shorter than upper link 22 contributes to reducing the size of the set of links and therefore that of casing 45.

  • the articulation axis 30 of the lower link 29 being placed in front of the orientation axis 33, after a significant rotation of the arm 3a around this axis 33, the axis 30 is no longer strictly parallel to the axis 23.
  • the relative offset between axes 23 and 30 would then lead to jamming of the joint common to the rods 22 and 29 if this joint were not produced by the ball joint 26, 27.
  • a slight bending of the ends of the rods 22 and 29 allows the center of the ball joint 26, 27 to be slightly offset from the top and bottom articulation axes 23, 30 while retaining perfect mobility at the scissor joint between the two links 22 and 29.
